We study single dibenzoterrylene (DBT) molecules embedded in 1,4-dichlorobenzene (para-dichlorobenzene, pDCB) at 1.2 K. Due to the relatively low melting point of pDCB (53 °C), this host-guest system can be easily prepared from the molten phase. Narrow linewidths, stable molecular lines and high saturation count rates of single DBT molecules were observed. For this reason, we consider this host-guest system a promising candidate for the study of interactions of single molecules with other small objects such as waveguides or nanoparticles.
我们研究了在1.2 K温度下嵌入1,4 - 二氯苯（对二氯苯，pDCB）中的单个二苯并苝（DBT）分子。由于pDCB的熔点相对较低（53°C），这种主客体系统可以很容易地从熔融相制备得到。观察到单个DBT分子具有窄线宽、稳定的分子谱线和高饱和计数率。因此，我们认为这种主客体系统是研究单分子与其他小物体（如波导或纳米颗粒）相互作用的一个有前景的候选对象。
